“…. B95-8 cells and Raji cells, both "normal" and TPA-induced, were stained with the same polyclotial rabbit antipapillomavirus serum using the avidinbiotin-peroxidase complex technique described by HWANG et al, (18). To con-firiTi the presence of EBV in the B95-8 cells and the TPA-induced Raji cells, parallel slides were stained with a mouse monoclonal antibody to the EBV early antigen EA-D (MAB 818, Chemicon Inc., Temecula, CA) using murine-specific reagents for the avidin-biotin-peroxidase complex detection.…”
